ATTORNEY Patented Oct. 27, 1936 UNITED STATES PATENT ori ice 2,058,519 serene MACHINE I, Peter Sivertsen, Cold Spring, N. Y. Application September 15, 1934, Serial No. 744,101 4c1 aims. (cine-102) This invention relates to attachmentsfor slicing machines and has more particular reference to attachments for the type of slicing machine in which the adjustable gauge plate regulates the 5 thickness of the slices. More particularly, the invention resides in the provision of means for holding the object when it is either irregularly shaped or has reached such small dimensions that it is difficult and dangerous to press the object 10 against the gauge plate withthe fingers for cut- 15 can be easily swung is inoperative position and locked in such position when not in use and easily unlocked and brought to operative position to bear on the object to be sliced when the latter has been nearly cut down to the end. More specifically stated, a transverse pusher member which generally conforms to the shape of the object holder is provided with a guide rod for slidably guiding the transverse pusher member in a direction lengthwise of the object holder, to push the object, the transverse member being arranged to also pivot around the guide rod to swing the pusher member from operative to inoperative position.

In the drawings accompanying this specifica- 6 tion one embodiment of the invention is illustrated, although it is to be understood that such embodiment is merely for the purpose of affording a clear understanding of the underlying principles of the invention, so that those skilled in the art may readily understand it without, however, limiting the invention to the specific details shown therein.

In said drawings:

Fig. l is a side elevation of the invention partly in section and partly fragmentary.

Fig. 2 is an end elevation of the invention when viewed perpendicular to the plane of the knife.

Fig. 3 is a partly fragmentary and partly sectional side elevation with the end holder shown in inoperative position.

Fig. 4 is a. perspective view of the end holder and chute.

Fig. 5 is a section of Fig. 3 on the line 55, of Figure 3, and

Fig. 6 is a modification of the locking arrangement shown in Figs. 3 and 5.

Continuing now by way of a more detailed description, an object holder A preferably has a V-shaped cross-section and may be inclined from the horizontal to afford a gravity feeding arrangement for the object to be sliced, although this particular invention may be used with equally good results in ahorlzontal or vertical type of machine, is supported ona bracket B secured to a reciprocating member 0 supported on suitable guide rods (not shown) so that the object holder A may be reciprocated. back and forth with respect to the rotary knife edge D, as is well understood; The plane, of the knife shown in the illustrated embodiment is inclined from the horizontal so that the object holder is arranged perpendicular to the plane of the knife in this particular instance. A transverse end member E having a plurality of projecting pins has preferably formed therewith and at oneside thereof, a guide sleeve G adapted to slide on a guide rod H having its opposite ends supported in brackets J and K formed with or attached to the holder A in such a manner that the guide rod is slightly spaced from one edge of the object holder and in parallel relation therewith. This arrangement permits the object holder not only to have a back and forth movement toward and away from the knife D but also permits the transverse member E to be swung about the guide rod H as an axis to an inoperative position, as shown in Fig. 3. The transverse member E is preferably shaped to conform to the inside of the object holder A and has a manually operable member L for manipulating it.

In order to prevent the transverse plate from being completely rotated to non-operative position except when retracted, the position shown in Fig. 3, a stop M which preferably consists of a metal strip secured to one edge of the object holder A, has its outer edge N so arranged that when the transverse member E is swung about the guide-rod H, the web P of the end holder strikes the edge N of the stop-plate M and prevents the member from dropping down too far. In order to permit the transverse member to take the home position below the object holder, as shown in Fig. 3, the stop-plate M is terminated at Q to permit the transverse member E, when it is pulled against the spring R, as shown in Fig. 3, to clear the stop-plate M and take a position where the latch S engages the keeper T, the spring R normally holding the latch and keeper in locked position.

Normally, the device is assumed to be in inoperative position as shown in Fig. 3, which leaves the object holder free to be used in the manner indicated in the Sivertsen Patent No. 1,480,572.

When the object to be sliced requires the use of the end holder for safety of operation, the

transverse member E by means of the manually operable member L is pulled back against the tension of the spring R, thereby releasing the latch S from the keeper T and permitting the transverse member E to be swung into position Within the object holder A. By permitting the transverse member E to slide toward the knife, the sleeve G reaches a position where, if the transverse member E is swung out of the object holder, the web P will engage the edge N of the stop member M so that the member E is prevented from swinging against the sides of the object holder A or other parts of the mechanism.

It is claimed:

1. An object holder for a slicing machine, comprising a V-shaped trough having oppositely inclined sides and a transverse end holder shaped to conform with the cross-section of the trough, a guide rod mounted on the top edge of one side of said trough, a sleeve integrally formed with one of the upper corners of the end holder, the sleeve being slidable on the guide rod and rotatable thereon to swing the end holder clear of the trough at any point along the length-of the guide rod, the top edge of said end holder having a generally horizontal portion when normally disposed in the trough and adapted to closely underlie one side of the trough when swung clear of the same for positioning wholly beneath the Vertical projection of the trough.

2. The holder as set forth in claim 1, wherein an elongated supporting member is fixedly mounted on the outer side of said wall parallel to said guide rod to support said end holder when it is swung clear of the trough at any point on the guide rod between the ends of said member, said member terminating inwardly of one end of said guide rod and trough to allow the end holder to be swung to retracted inoperative position beneath the vertical projection of the trough.

3. The holder as set forth in claim 1, wherein an elongated supporting member is fixedly mounted on the outer side of the said one wall of said trough parallel to said guide rod and said end holder has the said one of its upper corners angularly extended to support the said sleeve on its free end so that the extension will rest on the edge of said sup-porting member when said end porting member.

1 4. The-holder as set forth in claim 1, wherein the said. guide rod is supported at its opposite ends in brackets spaced inwardly of the ends of the said one wall of said trough and a coiled spring is engaged on said guide rod in abutting relation; to one of said brackets to act as a buiTer for said sleeve when said end holder is moved to retracted position on the guide rod, said trough'having a latch member disposed in fixed opposed relation to said spring and said end holder asecond latch member adapted to engage with and disengage from the first named latch member by a cam-like action between the latch members in cooperation with said spring during reversed swinging motions of the end holder to and from retracted inoperative position.
